Brazing furnace manufacturers to tell you brazing furnace processing and skills
1, before opening, to ensure that water, electricity, gas in the working state. Voltage at 380V, no 10% deviation. Pressure at 0.6Mpa, water pressure to the lowest value (0.5MPa). To meet the above requirements before they can power, to operate.
2, before discharge, check the equipment heating room, heating room must be clean, no debris, dust, oil, water and so on. In the inspection of the product, the same dry and clean, no water stains, oil, etc. in the discharge before the need to clean and clean.
3, after loading, the knob hit the "door off" position. Then, start the "mechanical pump" and "roughing valve". Vacuum units and furnace suction, while opening the vacuum gauge power supply (in general, the vacuum gauge power supply with the main power to start).
4, when the vacuum is higher than 1000Pa, the vacuum gauge monitoring point "J2" lit. This time, you can open the "Roots pump". If the conditions are not, "Roots pump" will not open, click the button no response.
5, when the vacuum is higher than 7Pa, the vacuum gauge monitoring point "J1" light. At this time, open the "front valve" and "diffusion pump". Preheat the "diffuser pump".
6, to be "diffusion pump" warm-up time to 90 minutes (can be observed on the touch screen counter), close the "roughing valve", open the "high valve", the furnace pumping high vacuum.
8, heating, insulation After the end of the entire process, "process end" alarm, at the same time, heating automatically shut down.
9, if you choose natural cooling, so that equipment as usual, until the equipment naturally cooled to the baked temperature, close the "high valve", "diffusion pump", "Roots pump", leaving only "mechanical pump" and " The "diffuser pump" is evacuated and cooled. At the same time you can put the knob to the "door open" position. When closing the "vacuum gauge", open the "manual bleed valve", to deflate, to the furnace pressure and atmospheric pressure balance, the door automatically open, you can take the material at the same time tighten the "manual release valve." To "cool the pump" temperature to room temperature (about one hour), you can turn off the "mechanical pump" and "front valve." Close water, electricity, gas. Complete the entire process.
